I currently have a material that has a render target being plugged into the normal channel. I for the life of me can not find a way to hide or make this texture invisible in viewport.
Unreal doesn’t allow texture samplers to be blank, so in the viewport, it’s using a black image, but this black image makes the whole object black as well, whereas I would like the object to look normal so that it can be texture painted, and edited in the viewport.
Safe normalize node with default value of (0,0,1)
This will test if the output of the render target is actually a vector, and if so it will normalize it. If it has a vector length of 0, it will use the default value provided as the normal vector instead.
